Every bicycle factories is characterized by their bicycle frame, while is also an standard equipment of a bicycle. Other components, such as: tires, wheels, pedals are other options. The Frame geometry governs the properties and performance as well. The lengths and angles of a frame affect the rider’s feelings and riding effect. This study attempts to rapidly verify the stress and displacement data of several types of bicycle frames by implementing line schema model，then analyze the Solid structure. First, establish the analysis results by line schema model; Second, inference the stress and strain of entity structure. Assuming that the initial conditions is the ideal State, and frame material is uniform, it is feasible to simulate entity structure and deformation by line schema model. The error condition is the identical. This study also developed a customized programming interface, and organized research results into structured files. This application can interactively display analysis result under different conditions of fixed frame. en_US dc.description.sponsorship 工業教育學系 zh_TW dc.identifier GN0697700368 dc.identifier.uri http://etds.lib.ntnu.edu.tw/cgi-bin/gs32/gsweb.cgi?o=dstdcdr&s=id=%22GN0697700368%22.&%22.id.& dc.identifier.uri http://rportal.lib.ntnu.edu.tw:80/handle/20.500.12235/99160 dc.language 中文 dc.subject 自行車（腳踏車） zh_TW dc.subject 固定式車架 zh_TW dc.subject 最佳化設計 zh_TW dc.subject Bicycle en_US dc.subject Bicycle Frame en_US dc.subject Optimization design en_US dc.title 自行車車架之結構分析與最佳化設計研究 zh_TW dc.title A Study on Structure Analysis and Design Optimization of Bicycle Frames en_US
